In trying to understand the structure of Dr Lecters memory palace, I was aided by Frances A. Yates's remarkable book The Memory Palace of Matteo Ricci.

In the garden of the hurricanes eye; is John Ciardis phrase and the title of one of his poems.

The first lines of poetry Clarice Starling recalls in the asylum are from T.S. Eliot's Burnt Norton,; Four Quartets.

My thanks to Pace Barnes for her encouragement, support and wise counsel.

Carole Baron, my publisher, editor and friend, helped me make this a better book.

Athena Varounis and Bill Trible in the United States and Ruggero Perugini in Italy showed me the best and brightest in law enforcement. None of them is a character in this book, nor is any other living person. The wickedness herein I took from my own stock.

Niccolo Capponi shared with me his deep knowledge of Florence and its art and allowed Dr Lector to use his family palazzo. My thanks also to Robert Held for his scholarship and to Caroline Michahelles for much Florentine insight.

The staff at Carnegie Public Library in Coahoma County, Mississippi, looked up things for years. Thank you.

I owe a lot to Marguerrite Schmitt: With one white truffle and the magic in her heart and hands, she introduced us to the wonders of Florence. It is too late to thank Marguerrite; in this moment of completion I want to say her name.
